Towards a super-resolution structured illumination microscope based on an array of nanoLEDs

This work presents a first prototype for a new approach to microscopy: a system basing its resolving power on the light emitters instead of the sensors, without using lenses. This new approach builds on the possibility of making LEDs smaller than current technology sensors, offering a new approach to microscopy we plan on developing towards super-resolution. The microscope consists on a SPAD based camera, a 8x8 LED array with 5x5 mu m LEDs distributed with a pitch of 10 mu m, and discrete driving electronics to control them. We present simulations of the system, as well as the first microscope prototype implementing the method, and the results obtained through it.
